As a partner running health checks for customers, one of the things we report on is the health of their process group structure.
Only being able to identify groups that have processes in them using reports provides a gap in our knowledge that has to be corrected manually each time.
If there was a report that would effectively generate the same data present on the governance page to a CSV (PUBLISHED PROCESSES, UNPUBLISHED PROCESSES,OUT OF DATE PROCESSES, SUGGESTIONS / FEEDBACK, RESPONSES REQUIRED, PROCESS VIEWS.
Getting this information as data that doesn't need potentially hundreds of clicks (the most recent time I did this there were ~160 subgroups that needed to be opened) would be absolutely fantastic.
